I spend more time thinking about algorithms than typing them, so I don't think my typing speed (which I never noticed to be significantly faster or slower than that of most programmers) matters a lot.

I worked with some programmers who did produce code at a high enough speed for their typing speed to make a difference, and in my opinion they were without exception extremely sloppy programmers, who produced large amounts of code that was buggy, difficult to maintain, badly documented, and often much larger than it would have been had they thought things through. They were excellent at producing something that works well enough to pass if it really needed to be up and running as soon as possible, though, I'm not saying people like that have no qualities, but it has a price.
